Nanofluidic memristors that rely on mechanical deformations to modulate ionic conductance can be coupled to form logic circuits, opening a route to ionic machinery that could implement neural networks.
Polycrystalline films of the non-toxic element bismuth exhibit a room-temperature surface nonlinear Hall effect, which could make devices based on topological quantum effects more practical.
Tapes whose adhesive force is controlled by ultraviolet illumination can be used to cleanly transfer large-area graphene, molybdenum disulfide and other two-dimensional materials with a low thermal budget and using no organic solvents.
By transferring laser-induced graphene to a hydrogel film at cryogenic temperatures, stretchable graphene–hydrogel interfaces can be created for application in wearable and implantable electronics.
An approach to soft electronics that is inspired by the emergence process of butterflies can be used to create devices that can recover from crumpling.
